CHARLES L. SPENCER, OF PROVIDENCE, RHODE ISLAND.

IMPROVEMENT IN NEEDLE-THREADERS.`

Specication forming part of Letters Patent N0. 58,314, dated September25, 1866.

To all whom 'it may concern:

Be it known that I, CHAELEs L. SPENcEE, of the city and county ofProvidence, in the State of Rhode Island, have 4invented a new andImproved Machine forThreadin g Needles; and I do hereby declare that thefollowing specification, taken in connection with the drawings making apart of the same, is a full, clear, and exact description thereof.

Figure 1 is a perspective view with aneedle threaded. Fig. 2 is aperspective view with the cap or cover thrown open, showing themannerthe needle is removed. Figs. 3, 4, 5, 6, 7, 8, 9, and l0 aredetailed parts. Figs. 1], 12, and 13 is another form of making aneedlethreader, coming apart in two halves to remove the needle, andheld together by two pins when in use. The principle being the same, Ishall not endeavor to describe lnore minutely.

In lheaccompanying drawings, A, Figs. l, 2, and 3 is a tube for thepurpose of guiding the needle to be threaded, one side of this tube isatteued and filed beveling. The hollow or needle-channel is partiallyfiled O' at the upper end, as shown in Fig. 3.

C, Fig. 4, is a dat spring made of any hard metal. b, Fig. 3, is a smallpivot for fastening spring O to the flattened surface of A.

At the upper end of the tube A is a projection, D, Fig. 3, and upon itstop surface is a tapered channel running to, and the small end of taperintersecting, the needle-channel, as shown in Fig. 7.

E, Fig. 5, is a cap or cover nicely fitted to the surface ofprojectionD, and fastened by a hinge. This cap or cover has a taperedchannel to match projection D, for the purpose of guiding the thread tothe needles eye when in use, as shown in Fig 8. At the small end oftaper on cap or cover E is a ridge or stop, F, Fig. 5, for the purposeof stopping the needle when its eye covers the small tapered hole thatguides the thread, as shown in Fig. l.

Fig. 6 is a small piece of wire for holding the hinge together.

Fig. 9 is an end View of tube A, showing the entrance for the needle tobe threaded.

Spring C is fastened to the tube A in such a manner that when the needleis pressed eye iirst through the channel the flat part of the needlecomesi'n contact with spring, and is guided so the needles eye is alwaysbrought in the right position to receive the thread.

The advantage of my invention over all other needle-threaders s, thatthe needle can be threaded at any and all times while one end of thethread is fastened to the work. As the thread is set free from thethreader by opening the cap or cover, the needle then can be removed atthe opposite end from that at which it is entered. In all others theneedle must be removed at the same end of threader at which it isentered, thus drawing the thread through the needle-channel, which wouldbe impossible to do if the opposite end of the thread was fastened toany kind of work.

I do not claim the spring as an improvement in needle-threaders; but
